Title

Visualization of minute signals in scanning probe microscopy data by EFA

Abstract

Scanning probe microscopy is a term expressing technologies that visualize surface characteristics of a sample by scanning probe over the sample and performing spectroscopy.[1] Some of them reach atomic resolution, and the characteristics at the atomic level constituting the sample can be observed. On the other hand, EFA (explolatory factor analysis) is a method of statistical analysis, which has a statistical model that divides obtained data into two types: the common factors and the specific factors.[2] Here, we focused on the fact that signals and noises included in the spectra obtained by measurement can be classified into the common factors and the specific factors, and visualized minute signals using EFA. I will give a presentation that we were able to visualize the minute signals in spectral data of various types of scanning probe microscopy.
